What It Is

CheckCheck is an online authentication service for the resale market covering luxury goods, sneakers, apparel, and collectibles. Sellers initiate a check through the App and take detailed product photos according to the instructions. Two professional authenticators then review the item independently; only when both approve does it receive a PASS, along with a downloadable or printable digital Certificate of Authenticity (COA). It is positioned not as an e-commerce marketplace, but as trust infrastructure for resale transactions.

Core Capabilities and Use Cases

The platform says it supports 365+ brands and categories, with more being added continuously. Authentication combines AI technology with human experts, focusing on serial numbers, materials, craftsmanship and construction, and provenance information. For TikTok Shop live sellers, CheckCheck emphasizes the ability to display proof of authenticity in real time during the sales process, improving transparency and buyer trust. For high-volume merchants, it offers CheckCheck for Business, including bulk pricing, financial guarantees, barcode scanning, an authentication dashboard, API, SDK, Webhooks, and Shopify integration.

Pricing and Fees

CheckCheck uses a credits-based pricing model: users need to top up credits before requesting an authentication. The page lists pricing from $6 per check and supports bulk credits as well as discounts for high-frequency merchants. In terms of turnaround time, the text mentions options such as 15 minutes or 4 hours, and also claims results can be delivered in as little as 5 minutes. If authentication cannot be completed, credits are automatically refunded, which is helpful for sellers trying to control wasted costs. However, the full price list, rush fees, and enterprise plan pricing are not disclosed in the main content.

Pros and Cons

The strengths are its dual-expert cross-review process, fast certificate issuance, category coverage suited to second-hand luxury and streetwear resale, and scalability features such as API and Shopify support. The drawbacks are that authentication depends heavily on photo quality, and if additional images are required, the timer restarts. The website also does not clearly explain supported regions, payment methods, service languages, or the full fee structure, so businesses should still consult the company before procurement.

Who It’s For and Access from China

CheckCheck is best suited to TikTok Shop live sellers, consignment stores, resale companies, marketplaces, and Shopify merchants dealing in second-hand luxury goods. Occasional individual sellers can also use it for single-item authentication. There is no clear information on access from mainland China, App availability, or local payment methods, so china_access can only be considered unknown. If it is not usable, sellers may consider local or platform-designated authentication services recognized in their target market as alternatives.
